#153 Run APLAWS+ under different context

[Brett]

This patch allows APLAWS+ to run under a context other than root.

It also adds support for running APLAWS+ under a secure https connection and better error reproting for XSLT errors. I added these additional changes with the patch because the files that were changed to add support for different contexts also contained the other changes.
